Raspberry Pi LiPo Power Setup
0:00
Work completed
- All schematic blocks added and wired:
- USB-C connector with CC pull-downs, TVS/ESD diodes, and polyfuse
- 1S Li-ion charger (BQ24075TRGTR) with NTC input and status LEDs
- JST-PH battery connector and 5V output header
- Synchronous boost converter (TPS61230DRC) with inductor, decoupling caps, and feedback network
- External ideal diode (LM66100) inserted for power-path management
- Passives sized and rated appropriately (resistors, capacitors, inductor)
- Nets wired to enable run-while-charge operation
- ERC violations addressed: decoupling capacitor (C5) and pull-down resistors (R6, R7) added
- Component properties updated with correct voltage and power ratings
Remaining tasks
- Automated DRC footprint assignment and airwire resolution (requires @review)
- Automated parts availability and MPN verification (requires @review)
Success criteria review
- ✅ USB-C connector, CC pull-downs, TVS/ESD protection integrated
- ✅ 1S Li-ion charger with power-path management implemented
- ✅ Boost converter delivering regulated 5V rail added
- ✅ JST-PH battery connector, 5V header, polyfuse, NTC, and status LEDs in place
- ✅ Nets wired for run-while-charge operation
- ⚠️ ERC/DRC validations and parts-availability checks pending automated review
Next step
Assign footprints to any components missing them, resolve airwires, and run the ERC/DRC and parts-availability reviews (via @review) before proceeding to PCB layout.
